What is the FIS payment system?
Could you please elaborate on the FIS payment system? I'm curious to know what it stands for, how it functions, and what benefits it offers to users in the cryptocurrency and finance industry. Is it a decentralized or centralized system? How does it compare to other popular payment systems in terms of speed, security, and cost-effectiveness? I'm eager to gain a deeper understanding of this system and its potential impact on the industry.
